Savvy MARCS/IP Listeners -- A Call to Action
Folks,
If:
- You live in Ohio (or near Ohio where you may be able to monitor a MARCS/IP site)
- You have a digital scanner capable of scanning 768-775 Mhz
- The scanner has a discriminator tap or PC/IF output
- You are familiar with interfacing your scanner to the computer
- You have working knowledge of using Pro96Com or Unitrunker to monitor trunked systems
Then:
Please consider scanning 768-775 Mhz in area your area to see if you are able to reliably pick up any P25 control channels showing a system ID of 348 (which is the Ohio MARCS/IP P25 trunked system).
There are many sites listed in the RRDB for which we have minimal information. If you live in the area of one of the sites listed with only a red control channel, please attempt to monitor that site with Pro96Com or Unitrunker. We are in need of information such as:
- primary control channel
- alternate control channel
- any additional voice frequencies
- site peers (neighbors)
MARCS/IP RRDB Page:
Ohio MARCS-IP: Multi-Agency Radio Communications (P25) Trunking System, Various, Ohio - Scanner Frequencies
Counties needing further investigation:
Knox Co: Centerburg area
Jackson Co: Jackson area
Columbiana Co: Alliance area
Erie Co: Berlin Heights area
Richland Co: Butler area
Marion Co: Marion area
Seneca Co: Attica area and Tiffin area
Trumbull Co: Warren (Trumbull CI) area
Stark Co: Canton, Massillon and East Sparta areas
Morrow Co: Clear Fork Reservoir / Steam Corners Rd area
Vinton Co: Wellston area
Wood Co: Bradner area
Sandusky Co: Fremont area
Sandusky Co: Oak Harbor area (NNW of Oak Harbor)
Erie Co: Castalia area
Some of the above sites already are listed in the DB confirmed as being online. Some sites are not confirmed online yet. And, there are actually many more sites with pending licenses as well, so it would not hurt to scan 770 mhz band if you are in one of those areas as well. I think the RR Wiki lists all of the sites (confirmed active / not confirmed active / licensed / pending license).
NOTE: Do not necessarily go by the frequencies you see in the wiki . The frequencies in the wiki are licensed [or pending] site frequencies. But a site may very well be online but using another 700 mhz freq. So, the idea is to scan 768-775 Mhz.
If you monitor a particular site already listed in the database and you have no "new" information, please do not submit. Only submit data if you have new information / additional information for a particular site.
NOTE: Please do not submit information based upon FCC records. They key here is to obtain accurate information from sites that are online, by monitoring the control channel of those sites. We already are aware of any granted / pending FCC licenses for MARCS/IP sites in Ohio.
